Sisaket lies on the southern rim of the Khorat Plateau, between the Mun river to the north and the Dangrek range along the Cambodian border to the south. For several centuries it was Khmer-speaking country on the northern edge of an empire centred at Angkor, and the physical record of that is still everywhere: brick and laterite sanctuaries in village compounds, most of them small, most of them standing where the community that built them stood.
What makes the province unusual in this guide is not the scale of its Khmer architecture but its afterlife. In Ayutthaya and Sukhothai the old monuments are enclosed in historical parks. In Sisaket the great majority were simply kept in use: a wat grew up around the prasat, the sanctuary became the compound's oldest building, and the two have shared a courtyard ever since. Four of the five Khmer monuments on this page are reached by walking into a working temple.
The record here is thinner than in Buriram, and this page says so rather than filling the gaps. One monument in the province carries a dated inscription in its own stone. The rest are dated on style by state registers, in Buddhist centuries rather than years. Several carry a registration citation that two state bodies write differently. None of the six had its opening hours confirmed from an official source by the run that wrote this file.
Every page keeps what a state register records apart from what is told about a place, and says plainly where a date is not established. That sentence is an asset here, not a gap.
5 of 6 temples in Sisaket are plotted. The others have no confirmed coordinate yet, so they are not shown as pins.
Every page is built from the National Office of Buddhism and Department of Religious Affairs registers, the Fine Arts Department’s national monument register and its published monographs, the Royal Gazette where it could be read, UNESCO, and the temples’ own material — with the Tourism Authority of Thailand used only for visiting practicalities, never for history. Nothing here is taken from a travel blog, a listicle or a review site.
The rule that governs every page is that recorded tradition is not history. Thai temple histories are full of foundation legends, and they are worth telling — but told as tradition, in those words, never flattened into a bare founding date. Where a date is not established, the page says so, and that sentence is the useful part.
Still to come here: Sisaket has far more registered and unwritten ground than six pages, and the first jobs of a second run are not new monuments. FIRST: open the Fine Arts Department register. Every ancientMonument field in this file is either null or carries a citation taken from the ONEP cultural-environment register rather than from the department's own register, because www.finearts.go.th and gis.finearts.go.th both returned 403 throughout — the fourth consecutive province. The Kanchanaburi run's method (QueryArcheologicalSite with a province id, which returns every monument in a province with its register status) is the tool, and it needs a run that can reach the host. SECOND: settle the 2478 citation, ตอนที่ ๗๕ against ตอนที่ ๒๕, by opening ราชกิจจานุเบกษา เล่ม ๕๒ itself; the conflict now spans two provinces and three monuments and is the single most repeated unresolved fact in this guide. THIRD: establish a coordinate for Prasat Ban Prasat at Huai Thap Than, the one monument here that ships with no map. FOURTH: walk ssk.onab.go.th with a rendering browser and harvest the iid values for วัดสระกำแพงใหญ่, วัดสระกำแพงน้อย (วัดเทพปราสาท) and the Huai Thap Than temple, which would close three royal-class and three nikaya gaps at once; the Wat Maha Phuttharam grade on this page came from that host and the route is proven. Then the monuments. The obvious six, in order: ปราสาทปรางค์กู่ (บ้านกู่, ตำบลกู่, อำเภอปรางค์กู่) — a three-tower brick sanctuary that is a DIFFERENT monument from ปราสาททามจาน on this page, in the same district, and the two are constantly conflated; ปราสาทเยอ at ไพรบึง; ปราสาทกุด inside วัดโพธิ์พฤกษ์ at ขุขันธ์; ปราสาทตำหนักไทร; ปราสาทภูฝ้าย; and ธาตุบ้านเมืองจันทร์, which sits inside a circular moated settlement and would be the province's first non-Khmer archaeological page. A separate and larger job is the Dangrek escarpment group — ปราสาทโดนตวล, ภาพสลักผามออีแดง and the paired stupas at เขาพระวิหาร — which this run did not attempt, because the national park containing them has been closed since July 2025 and a page that sends a reader to a closed military frontier is worse than no page. วัดล้านขวด (วัดป่ามหาเจดีย์แก้ว) at ขุนหาญ, the temple built from over a million glass bottles, was considered and NOT built: it is genuinely remarkable and it is a modern foundation, and no state register entry for it was reachable this run — the same source-chain problem, not a research one.
